Climate change, water, and land management affect the terrestrial water cycle and river flow. They do so through changes in precipitation and evaporation, aside from a multitude of other land surface processes. Earth system models are routinely used to simulate and detect globally observed changes and attribute these changes to climate change. Attribution is based on an assessment of the consistency or inconsistency of change signatures by including or excluding hypothesized drivers of change in process-based models (1). On page 1159 of this issue, Gudmundsson et al. (2) compare the consistency that globally observed trend-patterns in mean river flow and hydrological extremes exhibit with regard to a set of model simulations.
